Konstantin Shvachko commented on HADOOP-5700: --------------------------------------------- I agree with Nicholas. We should reverse the patch. The problem is solved by a simple one line change: {code} /** Convert strings to byte arrays for path components. */ static byte[][] getPathComponents(String[] strings) { - if (strings.length == 0) { + if (strings == null || strings.length == 0) { return new byte[][]{null}; } {code} > INode.getPathComponents throws NPE when given a non-absolute path > ----------------------------------------------------------------- > > Key: HADOOP-5700 > URL: https://issues.apache.org/jira/browse/HADOOP-5700 > Project: Hadoop Core > Issue Type: Bug > Components: dfs > Reporter: Todd Lipcon > Assignee: Todd Lipcon > Priority: Minor > Fix For: 0.21.0 > > Attachments: HADOOP-5700.txt > > > If you pass a path that doesn't start with '/' to INode.getPathComponents, it > throws a NullPointerException. Instead it should throw > IllegalArgumentException to make it clear that absolute paths are required in > this code. > The attached patch fixes this, clarifies, the javadoc, and adds a test case. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
